+/* This test checks that a TRRServiceChannel can connect to the server with
+   a proxy.
+   Steps:
+     - Setup the proxy (PAC, proxy filter, and system proxy settings)
+     - Test when "network.trr.async_connInfo" is false. In this case, every
+       TRRServicChannel waits for the proxy info to be resolved.
+     - Test when "network.trr.async_connInfo" is true. In this case, every
+       TRRServicChannel uses an already created connection info to connect.
+     - The test test_trr_uri_change() is about checking if trr connection info
+       is updated correctly when trr uri changed.
